Q0422 Torque Dampers - Compact

Important Notes

Rated torques measured at rotation speed of 20rpm, at 23°C.
Values ±20%.
Max. rotation speed 50rpm.
Max. cycle rate 10 cycle/min.
Operating temperature, -5° to 50°C.
Design tested to 50,000 cycles.

Torque calculation:
T(Kg.cm)=W(Kg) x H(cm) x 9.8/2.
W(Kg) is weight of cover/lid, H(cm) is distance between fulcrum and cover/lid's opening edge.

Q0422 is designed to generate a large torque just before a lid, closing
from a vertical position; comes to full closure. See diagram a.

Q0422 should not be used for a lid closing from a horizontal start position, as the damper torque generated, just prior to closing, is too great causing the lid not to fully close. See diagram b.
